An Open Source Lego Robotics System
I created this Lego robotics system for my robotics camp, Kev-Bots. It is based on the ESP32, a microcontroller with built-in WiFi and Bluetooth capabilities. I built all of my code on top of the Dabble Game Controller ESP32 library from STEMpedia. I used Fusion to 3D model mounting hardware for generic servos that can be easily found on Amazon. Although these motors may not be the cheapest option, they were what I had on hand, and they are very plug-and-play, with no extra setup needed (in the future, I am going to model mounts for basic DC motors). I also found models for Lego-compatible gears. I 3D printed all of these components on my Bambu Labs P1S. All of the other components I used can easily be found on Amazon. They included a USB battery bank to power the ESP32, and a 4 x AA battery bank to power the servos. I also soldered together connector cables using Dupont jumper wires. The final result is a system of parts to easily integrate high-torque servo motors into Lego projects, which are controlled by a Bluetooth controller app for iOS and Android. All of the files can be found on my github
